DREDGlNG-BUCKET.

Specification of Letters Patent.

Patented March 6, 1906.

Application filed October 27. 1905. Serial No. 284,612.

To all whom it may concern.-

Be it known that I, CHARLES A. MORRIS, a citizen of the United States, and a resident of Bloomfield, in the county of Essex and State of New J erseey, have invented certain new and useful Improvements in Dredgin Buckets, of which the following is a speci cation.

This invention relates to improvements in dredging-buckets, and has particular application to types of buckets commonly known as the clam-shell or orange-peel buckets.

My invention consists in the construction, combination, and arrangement of parts set forth in and falling within the scope of the a pended claims, and while I have herein s own and described certain preferred forms of the invention I wish it to be understood that I-do not limit myself to the precise details set forth, as there may be modification and variation in the construction and arrangement of parts without departing from the spirit of the invention or exceeding the scope of the claims.

In the accompanying drawings like characters of reference indicate like parts in all the views.

Figure 1 is a view, partly in elevation and partly in section, of a closed bucket embodying my improvements. Fig. 2 is a view showing the bucket in open position. Fig. 3 is a view in end elevation of the bucket shown in Figs. 1 and 2. Fig. 4 is a top view of the same. Fig. 5 is a view in side elevation. Fig. 6 is a detail view of the portions of the shaft-operating mechanism. Fig. 7 is a view in side elevation of a modified form of bucket. Fig. 8 shows such bucket in open position. Fig.9 is a top view of the same. Fig. 10 is a view in side elevation of still another form of bucket. Fig. 11 is a view showing a bucket such as shown in Fig. 10 in its open position ready to receive a load. Fig. 12 is a top view of a bucket shown in Figs. 10 and 1 1. Fig. 13 is a view embodying a conventional illustration of a hoisting-engine and showing the connections between said engine and the bucket, this view being intended to illustrate one manner of operating such bucket.

Referring now to the accompanying drawings in detail, and particularly to Figs. 1 to 6, inclusive, the numerals 5 5 indicate the two sections of a bucket, each section having a pair of oppositely arranged inwardlyin-- clined side arms or brackets 6 6, all of said arms being connected by the ower-shaft 7 of the bucket passing throng the ends of said arms, said shaft being maintained in position by washers 8 8 and cotter-pins 9 9, the construction being such that the two sections of the bucket are connected by a common pivot, whereby such sections may be opened and closed. Rigidly secured upon the shaft at approximately the central ortion thereof and adapted to turn therewitli aretwo ro edrums 10 and 11, the drum 11 being pre erably greater in diameter than the drum 10, so that more rope will be wound on this drum in one revolution of the shaft than is wound 7 o on the drum 10. The numeral 12 indicates a line for hoisting and closing the bucket, but shall be hereinafter for the sake of convenience termed the closing-line, "such line being secured to the drum 11, while 13 indi cates the openin -line of the bucket, connected at one en to the drum 10. Both of these lines lead off to a suitable source of power, such as the drums of a hoisting-em gine, conventionallyillustrated in Fig. 13, said engine, which is shown at A, having drums B and C, respectively. The line 12 passes to the drum C, while the line 13 passes to and is operated by the drum B. These two drums are operated in a well-known manner 8 5 and the engine may be of any preferred type.

In order to impart movement from the power-shaft 7 to the bucket-sections to operate the latter to open and close, I may employ the following arrangement of parts and mechanisms: In Figs. 1 to 6 the numeral 14 designates a casing or boxing supported from the shaft 7. Extending transversely through the casing and journaled therein are the studshafts 15 and 16, the shaft 15 carrying a gear- 9 5- wheel 17, turned at the pinion 18 on the power-shaft 7. The revolution of the gearwheel 17, which is fast with the stud-shaft 15, of course turns the latter, which also carries a gear-wheel 19, meshing in turn with the IOO gear-wheel 20 on the end of the shaft 16: On each of the sections 5 5 of the bucket are formed lugs or perforated ears 21 21, and to each pair of ears there is secured one end of a rack-bar 22 by means of a pivot23. One of 10 5 said rack-bars is intended to engage with the gear-wheel 17, while the rack on the 0 pcsite section engages with the gear-whee 20.

v To hold these rack-bars in proper condition shaft and drums the drum to which the opening-line is secured and 11, as is shown in in contact with their respective ears, I may Figs. 1 to 6, inclusive, I provide a plurality of employ guides 24, and as each of said guides bearing-plates 14, spaced apart by and supis a counterpart of the other a description of porting the ear-shafts 15 and 16. The opone is sufficient for both. 25 is a plate, in eration of t is bucket is substantially the the present instance triangular in form, sesame as that heretofore described in Figs. 1 cured to the shaft of the ear, for the rack of to 6.

which gear it is intende to act as a guide. In Figs. 10, '11, and 12 I have shown still This triangular plate extends beyond the peanother modification of my device. In this riphery of the adjacent gear-wheel and carcase the sections 5 5 are provided with segries guide rollers 26 26, adapted to bear mental racks carried by the webs the same as a ainst the back or the non-serrated portion in Figs. 7, 8, and 9, with the additional feao the rack to guide the latter. ture that such webs are provided with braces The above is a description of the mechan- 27, extending diagonally from the segmental ical construction of my bucket, such as shown rack portion of the web to the power-shaft 7,

in Figs. 1 to 6, inclusive, and I will now prosaid braces having apertures to permit the ceed to describe briefly the operation of the passage of said shaft. In the case of this same. When empty and suspended in a nonbucket the drums 10 and 11 are arranged working position, the bucket is normally near the ends of the shaft, with the operatingclosed. Now if it be desired to open the gearing interposed therebetween. This gearbucket and lower the same to receive a loa ing comprises a pinion 18", meshing with the ge ar-wheel 17 a which is relatively wider than is actuated and the pull on the line revolves said gear 18, and also in turn meshes with the power-shaft 7 in a direction to open a secthe gear 20*, carried by the shaft 16. A short tion of the said bucket in the position shown stud-shaft 15 supports the relatively wide in Fig. 2. The bucket is then ready to be gear-wheel 17. The supporting-frame for lowered, and this is accomplished by paying the gears in this instance is also formed of out the hoisting-line, the opening-line being two triangular plates spaced apart,said plates also paid out sufficiently to restrain the secbeing indicated at 14) 14:". Extending from tions of the bucket from closing. The bucket the sides of said plates 14 14 are projections 9 5 is then lowered into the material and closed 28 28, each carrying a vertically tubular by taking in the hoisting-line of the engineguide 29 and 30, arranged adjacent to the drum, which tends to pull the sections todrums 10 and 11, respectively, so that the gether by revolving the shaft in the direction hoisting and opening ropes may pass thereopposite to which it is revolved by the openthrough to the drums, such arms having a ing-line. As soon as the bucket is closed the tendency to guide the rope and maintain it in two lines are then taken in by the engineits proper position and also avoid such rope drums, sufficient tension being maintaine becoming entangled with any of the operating mechanism of the bucket.

When tion of this bucket is substantially the same to 5 the bucket has reached the point where the as that heretofore described for the two prematerial is to be deposited, the taking in of ceding forms, and it is unnecessary to reiter ate the same in detail.
